If a particular application requires pulseaudio, install the apulse package, and start that application through apulse. One thing I haven't seen mentioned so far is to make sure that each user who is supposed to be able to play sound is a member of the audio group. If they aren't in the audio group, add them to the audio group, log them out, and log them back in. Note, I get sound in Beowulf in firefox just fine with out pulseaudio installed. > 3) The 'play' utility from the sox package gives an error whenever I try to > play an mp3 file.

Better yet, unless you have some reason not to, just install the libsox-fmt-all package. For playing music from the command line, I use mplayer. As you've discovered, aplay works too, and play should work as well once you install the necessary format support.

Pulseaudio is a land of a thousand hidden mutes, and a maze of state dependencies. So I de-installed Pulseaudio several years ago. At the end of this email I'll tell you about my latest Pulseaudio disaster. > 1) If anyone can tell me how to get pulseaudio to see my built-in > audio for all three logins, it would be greatly appreciated. Reboot. Then, every time Pulseaudio fails, reboot. Pulseaudio is a maze of state dependencies. > > 2) How do I get pulseaudio to run for each user when they log into > the system. Put the command to start it in each user's .bashrc, or in each user's .Xdefaults and .xinitrc, or just have sysvinit or runit run the daemon for all users (if all users can share Pulseaudio). [snip] I heard you loud and clear when you said you want your family to have the exact same experience in Devuan that they had in Debian. Unfortunately, Pulseaudio is very connected to dbus and I think somewhat connected to systemd. So what I'd do is: 1) Uninstall Pulseaudio and Pavucontrol 2) Create /usr/local/adjustments 3) Install apulse, the app at a time Pulseaudio replacement 4) Create executable script /usr/local/adjustments/firefox containing following code: apulse firefox 5) Put /usr/local/adjustments at the very front of the path, and make sure it stays there. 6) Use /usr/local/adjustments for any other programs that have irresponsibly required junk software.

IIRC the specific complaint wasn't that they checked for rDNS, but that they matched it against the domain of the sender. That makes no sense at all, it prevents running more than one domain on one mail server. I also use lack of rDNS as a check. I also check it for obvious misconfigurations like (from memory) : it's an IP literal (not allowed by RFC), it's not one of my domains, the domain actually exists. But one thing I don't check is that the rDNS matches the name given by the server in it's greeting - that just gets too many rejections because to many supposedly professional IT people can't get basics right. And I don't just mean "little guys", some of the problems I've seen with DNS and mail servers have been from larger outfits where I know they employ sizeable IT departments.

But then you : a) lose all visibility of what happens to your mail One of the reasons I use my own mail server is because I can then see exactly what's happening to my mail. Especially if it's not getting delivered - which these days doesn't generally seem to be a problem, even for AOL ! It also means I have evidence from my logs. On a number of occasions I've used this along the lines of "as per which was delivered to your mailserver on " when dealing with people who have "conveniently lost" previous communications. b) are reliant on your ISP being capable of running a mail server reliably. I don't think I'm alone in finding ISP mail server offerings to "have shortcomings". I've personally lost mail due to incompetent ISPs. As previously mentioned, unless you are expecting an email that doesn't arrive, you don't know you've lost it. I went through a phase where my ISP was losing mail, but only intermittently. It was only when I could pinpoint something missing, and the sender was tech savvy enough to be able to give me their server logs, did my ISP finally consider I had a complaint to investigate - they then went and changed my settings in their control panel to wrong settings, and lost mail that they'd had queued on the wrong server for some time (triggered delivery without any notice, but from the wrong server and my server rejected them as it only allowed mail specific servers (the ones they listed as inbound relays)). But then, having run mail servers for some years now, I can really really understand the desire to make it an SEP (Someone Else's Problem) !

The issue that I am having is with sound. My daughter reported that
it was not working. I tried playing a video (in Firefox) from my
login and also got no sound.
Me too when installed beowulf I had problems.
Pulseaudio brings trouble and has odd behavior.
Alsa it is not without problems.
However both works with no|a little|medium effort.
I don't like pulseaudio and in my machines tend to remove it. Sometimes
install it with disgust.
I have since determined that pulseaudio was not running (it is
installed). So I started the pulseaudio daemon under my login,
started up Firefox and played a video. Sound. Yay! I logged into my
daughter's account and started the pulseaudio daemon, started Firefox
and played a video. No sound. Boo!
The I started pavucontrol under both logins. My login shows the
'Built in Analog Stereo' output device, and its monitor for input. My
daughter's login shows a 'Dummy' output device and its monitor for
input. under my wife's login, it shows the same 'Dummy' devices as my
daughter's login .
1) If anyone can tell me how to get pulseaudio to see my built-in
audio for all three logins, it would be greatly appreciated.
You need to make a file named .asoundrc in home directory and select
correct audio card.
You can find it with:
cat /proc/asound/cards
You may insert a number or (best) the name of audio card.
For info:
https://www.alsa-project.org/main/index.php/Asoundrc
pulseaudio is alsa based and it should work.
2) How do I get pulseaudio to run for each user when they log into the
system.
I recommend you not to waste time configuring pulseaudio. If pulseaudio
don't work and troubleshooting is more difficult than expected remove it
and configure alsa. If alsa work then:
if is necessary (advanced mixing, trouble with pulseaudio only software
as firefox, other...)
install pulseaudio
else
install apulse (sound working in pulseaudio only software as
firefox for example), configure dmix plugin in alsa and so on...
end if
3) The 'play' utility from the sox package gives an error whenever I
try to play an mp3 file. Using 'aplay' to play .wav files works
fine. What do I need to do to play mp3s from the commandline?
You can try:
vlc -Incurses FILE
or moc (it also works by freeing the terminal):
http://moc.daper.net/
(NOTE: I boot to console only. Each user switches to a different VT
and runs startx from there.)
Yes, me too run X from VT.

I had some entertainment dealing with this problem over the years.
When I switched to Devuan I had to tinker a bit. I can't remember any
of the details, but this is what I ended with in my zsh login script:
string="$TTY"
# I don't know why this works, even though $TTY is actually /dev/pts1
pattern='/dev/tty'
tty_to_use=''
# I could rewrite this in POSIX sh if someone needs
tty_to_use="${string##${pattern}}"
tty_to_use="${string##*${pattern}}"
xinit /etc/X11/xinit/xinitrc -- /usr/bin/X :$(( tty_to_use - 1 )) \
vt"$tty_to_use" -auth "$( \tempfile --prefix='serverauth.' )"
logout
xinit parameters sometimes needs tuning.
I use my script for start X (don't use startx).
In beowulf just upgraded xinit with usual parameters (ascii works well)
don't work.
I digged inside startx script and get this:
# Automatically determine an unused $DISPLAY
d=0
while true ; do
[ -e "/tmp/.X$d-lock" -o -S "/tmp/.X11-unix/X$d" ] || break
d=$(($d + 1))
done
defaultdisplay=":$d"
unset d
and I added this:
if tty|grep "/dev/tty[0-9]*" >/dev/null ; then
VT="vt`tty|grep "/dev/tty[0-9]*"|sed 's/\/dev\/tty//g'`"
else
printf "Virtual terminal not found.\n"
return 1
fi
Passing $defaultdisplay (display number) and $VT (virtual terminal) X
start without problem.
If anyone really really wants to dig through my history of desperate
experimentation throughout multiple Linuxes:

Thanks interesting.
